Before you can access another person's calendar, contacts or inbox they will have to grant permission to use their email account to you.
Once they have done this, continue below.
Opening another person's folder with Outlook
If you use the Open Other User's Folder method as outlined, only the primary Outlook folders (contacts, inbox, Journal, Notes, Tasks) may be accessed; sub folders are not available. In order to access folders other than Primary Outlook folders, they must share their entire mailbox.
